7 To aZZ whom it may concern I Be itlmown that I, HER E T 3M.- STURGIS, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Mop Heads and Fasteners Therefor; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

, This invention relates to mop heads and fasteners therefor, one of the objects being to provide an efficient method of attaching mopsto handles whereby the mop head and handle may be conveniently secured together and disassooiated whenever the occasion demands.

In the drawings,

Fig. 1 is an elevational View of a mop providedwith a head connection constructed in accordance with my invention.

Fig. 2 is a perspective view of the mop head and the coupling detached.

Fig. 3 is a longitudinal, sectional view through the coupling member and mop head. Fig. 4 is a detail perspective view of the coupling collar, and

Fig. 5 is a detail perspective view of a slightly modified form of mop head adapted to be engaged by the type of coupling shown in Figs. 1 to 4.

In carrying out the invention I provide a handle 1, which may be of usual construction and secured to one end thereof is a sleeve or ferrule 2, extending slightly beyond the end of the handle and enclosing the longitudinal grooves 3 and 4, which are adapted to receive the elongated pins or studs 5 and 6 of the mop head fastener. The prongs 5 and 6 are continuations of the staple or fabric holder loop 7, which bind the fabric to the head portion 8, shown as comprising a concavo-convex member, the peripheral, outwardly flared flange 9 of which embraces the mop fabric 10. r

The mop head, consisting of the disk 8 and its flange 9, is provided with oppositely disposed lugs or projections 11 and 12, struck out from the metal of which the i head consists, preferably a die operation.

The lugs 11 and 12 are adapted .,to' be en-" gaged by a coupling -sleeve13, mounted upon the ferrule 2 and having-inwardly project ingcam flanges 11d and 15., the respective ends of they flanges beingspaced apart, as at 16, the spaces 16 being substantially equal to the widths'of'the projections 11- and 12,

which are adapted to be received in the notches l7 "and 18 oftheferrule 2, the end of the ferrule being provided with semi-cincular flanges 19 and-20, as seen in=Fig. 2.} .The prongs 5 and 6 are connected to the loop portion 7 byoffset portions 21 and-22,

dinal play of the disk: in one direction, the play of the-disk in the opposite direction being opposed .bythe filled-in portion 23 of the mop fabriclO,

'which constitute locks to prevent lo'n'gitu- "When the parts are properly assembled and it is desired to attach the mop head to the 'handle,'the two prongs 5 and 6 will be introduced into the grooves or recesses-*8 and 4 withthe lugs Hand 12 in'the spaces ,7

17 and 18. Then the coupling ring 13 will be moved longitudinally of the ferrule-'2 until the lugs have passed through the spaces 16, whereupon the ring 13, which is preferably milled, will be turnedso that the camv fiangesll and 15 bind on the'lugs and draw the head into the socket 24, formed bythe protruding ends of the ferrule 2 until the flanged portion 9 rests upon the flanges 19 and 20, whereuponthe head will be locked to the handle.

If it is desired to release the head from the handle for any purpose, the coupling ringcan be turned until the spaces 16 register with the lugs 11 and 12, whereupon the head may be detached. i

In Fig. 5 I have showna slightly'modiplicable for use in connection with the socalled cedar mops. In this form a trian'gu-f 95 fied form of mop head, particularlyapprongs or projections corresponding to those designated 5 and 6 in the preferred form.

What I claim and desire to secure by LettersPatent is:

1. ln'combination, a mop labric supporting head having diametrically opposite lateral projections, a handle having a fixed ferrule thereon, the end of which projects beyond the handle to form a socket, the edge of the ferrule having a peripheral flange intersected by projection receiving notches cut in the Walls of the ferrule, and a cam ring. on the ferrule for engagement with the under faces. of the projections to locate them. inthe recesses.

2. In combination, a mop fabric supporting headcomprising a con'cavmconvex plug, an adjustable loop member carried. by. the head to support a mop. fabric, a handle having a socket to receive the plug, the Walls of the socket having vertical. cut-out portions, lugs on the'plug projecting through the cut-out portions, and a cam ring on the handle having means for engagingthe outer taceso'f the projections to retain the plug dle having; recesses to receive the free ends of the staple, and means for lockingthe head to thehandle.

5. In combination, a mop head comprising a concave-convex disk, a' mop fabricengaging staple projec'ting'through said disk and having offset portions to prevent longitudinal movement of the staple, ahandle having recesses to receive the free ends of the staple, means'on the handle to prevTen-t rotative movement of the head, and

.means for locking the handle and head together.

in combination, a mop headcompr1sa disk having oppositely projecting lugs,

means for securing a mop fabric to the disk, a handle, aierruleon the handle having oppositely located recesses to receive the lugs or projections on the disk, and a cam ring on: the handlehaving cam flanges to ride over the lugs to dra-W the head into intimate contact with the handle.

7. The combination with a mop head comprisinga disk having a staple projecting therethrough, the loop of which serves as a mop fabric hinder, the ends of the staple projecting throughthe disk, lugs on the disk, handle having longitudinal recesses to receive the projecting ends of the staple, a ferrule surrounding the recesses and extending beyond the l'rand le member-to form a socket to receive. tl rehead, opposite portions of the i' errul'e being notched to receive the lugs or projections on the head so that the head cannot turn with: respect to the handle, and a ring on the ferrule engaging the lugs or projections on the head to draw it into the socket.

in testimony whereof I affix IEIERBERT M. STURGIS;

my signature.
